I'm curious if you've ever promoted your content on AdWords to get links to it. If so, how did it do?
Have you tried other ad platforms for promoting your content?
I'm familiar with Marty Weintraub's Facebook case study that got them an article in Ad Week as well as the MozCon (or Linklove?) preso about Outbrain and Taboola type related content network promotions ... curious if folks here have done this successfully, however and what results were like if so.
